METHOD FOR DETERMINING ZONES INSIDE OUTER BRICK WALL FENCE, CHARACTERIZED BY QUASI-STATIONARY CONDITIONS OF HEAT TRANSFER AT FIELD EXPERIMENTAL STUDIES IN WINTER

摘要

FIELD: measuring equipment.;SUBSTANCE: method for determining zones inside the outer brick wall fence, characterized by quasi-stationary conditions of heat transfer at the field experimental studies in winter, comprises measuring the temperature of the inner and the outer surfaces and throughout the structures thickness by placing the sensors in the fence thickness. Herewith the appearance process of the zones with quasi-stationary conditions of heat transfer in the fence thickness, is simulated during the day in the presence of the outdoor air gradient (t) according to the sensor indications by using the vector direction of the temperature gradient. Then the nature of the heat flow oscillations is considered according to the temperature changes on the surface and in the fence thickness, from the outer fence layer into the inner layers, determining the zones occurring in the fence thickness and providing the required conditions of the quasi-stationary heat transfer.;EFFECT: expanding the determination range of the fencing structure thermophysical characteristics.;8 dwg
